View a graphical chart of file and folder sizes with Disk Inventory X

I prefer WhatSize, myself. I find it easier to drill down and find where the space is actually being used. The graphic representation is neat, but not as useful.

Still waiting for someone to create a Mac port of Filelight (http://www.methylblue.com/filelight/).

A useful workflow I recently discovered: you can drag folders onto the app icon and it will start up showing just that folder.

Excellent app!

This app is great. I'm getting to the limits of my 30GB drive on my ibook and I'm looking for stuff that I can put onto my external drive without missing it. If i get rid of iDVD adn the encyclopedia that I've never used, I'll have 2 gigs right there.

I have the same question an Uncle Jerry, though. Does anyone know how to tell what's safe to delete? I hope I don't mess anything up.

Does it keep you from tossing out files that you NEED to keep your system running? I would hate to delete something that I wasn't supposed to. But then I guess you should leave it alone if you don't know what it is...

I've been using this for awhile, and I must say its GREAT, if a bit slow. Oh well, it does its job and does it well, even if it lags a bit (which is completely understandable for what it is doing).

It's AMAZINGLY helpful. Great, great appliation! I found all kinds of files I didn't need anymore, in all kinds of places.

One of my most used apps, absolutely love it. Wonderful piece of software, really great stuff.
